| Calcium is in Group II-A. It loses two electrons and forms a
+2 ion called an calcium ion. Nitrogen, of course, takes on a -3 charge to form
a nitride ion. The charge ratio is 2:3 therefore the atom ratio will be
3:2. Since three calcium ions each with +2 charge will
neutralize the charge on two nitride ions with -3 charge, the formula will be
Ca3N2.
The name is calcium nitride because it is made from calcium ions and
nitride ions. |
